HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 724, 473, 224 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 724, 473, 224 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 724, 473, 224 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 724, 473, 224 is 1.
HCF(724, 473, 224) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 724, 473, 224 is 1.
Step 1: Since 724 > 473, we apply the division lemma to 724 and 473, to get
724 = 473 x 1 + 251
Step 2: Since the reminder 473 ≠ 0, we apply division lemma to 251 and 473, to get
473 = 251 x 1 + 222
Step 3: We consider the new divisor 251 and the new remainder 222, and apply the division lemma to get
251 = 222 x 1 + 29
We consider the new divisor 222 and the new remainder 29,and apply the division lemma to get
222 = 29 x 7 + 19
We consider the new divisor 29 and the new remainder 19,and apply the division lemma to get
29 = 19 x 1 + 10
We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 724 and 473 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(29,19) = HCF(222,29) = HCF(251,222) = HCF(473,251) = HCF(724,473) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 224 > 1, we apply the division lemma to 224 and 1, to get
224 = 1 x 224 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 224 is 1
Notice that 1 = HCF(224,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
